Magnetism of the easternmost segment of the American-Antarctic mid-ocean ridge

Results derived from the combined studies of the anomalous geomagnetic fiel d and magnetic properties of ocean-floor rocks from the American-Antarctic mid-ocean ridge in the Bouvet triple junction region. The northeastern term ination of the ridge is shown to be under conditions of an "undernourished" rift, which transforms the ridge into a complexly deformed depression stru cture.
